Making a bootable CD from a bootable USB flash drive

[sshoji]

I want to make a bootable CD from a bootable USB flash drive.

I have a working bootable USB flash drive. I guess I need to know how
to get
from the USB drive to an image file (ISO, BIF etc) , then I can burn a
CD from the image file. (I've tried Magic ISO, but it doesn't seem to
do it. It only seems to work for drive A: floppies) I've tried setting
the USB as first boot device, but it doesn't like that.)

Any help? Thanks in advance.

question: what do you mean by a "bootable USB flash drive"? Does it
mean that you boot from the USB drive? What OS do you boot, xp?

If you boot from you USB drive, than from what I know, a master boot
record (mbr) comes into play. and image file alone wouldnt work then,
as far as I know, you somehow need to get the MBR across.

Yes, I can boot the computer with my USB flash drive. (ran Fdisk,
format (windows 98), fdisk /mbr and copied files, and that's fine) It's
for a DOS Symantec Ghost client disk. (which doesn't fit on a single
floppy, or it would be easy to make a bootable CD from a bootable
floppy)
Using Magic ISO, I can make a boot image from a bootable floppy, but
not a USB drive. I can use the floppy for the boot record, then add
the other files later from the USB drive, such as the autoexec, then
burn the CD. The files from the floppy and those added later seem to be
in different 'sessions' and the autoexec doesn,t run (but i can see it
on the CD)
Does this make any sense? Thanks.

You must add or modify the autoexec or any other file that belongs on the
virtual "A" boot image before you burn the CD, the autoexec won't run if you
add it as data to the bootable CD.
